To all IIILO'IIL it may concern Be it known that I, CllAlilJj-IS S.LOCKWOOD,

a citizen of the United States, residing at 496- Clinton avenue, Newark,county of Essex, and State of New Jersey, have invented cer-l tai'n newand useful Improvements in Rollerllea rings for Side and End Strain.fully described and represented in the following specification and theaccompanying draw- .mgs, forming a part of thesame.

The object of this invention is to furnish a roller bearing adapted toresist lateral and end strains, and this object is accomplished byforming a hub with a cylindrical seat and a conical scat adjacentthereto and tapering sets of cylindrical and tapering rolls respectivelyto the said seats with a cageto keep them in their working relation, anda casing applied to their' exteriors. 'l he cylindrical rolls resistlateral strain, and the tapering rolls operating with the tapering seatin the casing serve to resist end thrust. Lateral strain and end thrustboth tent, to crowd the tapering rolls upward upon the tapering seat ofthe, hub, and the adjacent ends of the cylindrical rolls are arrangeditocontact with the adjacentends of the tapering rolls, and eachcylindrical. roll. is provided with-a. col lar bearing upon a shoulderon the hub to resist the sliding tendency of the thrust rolls. To securea frictionless contact between the cylindrical and thrust rolls, theends of the cylindrical rolls next the junction of the hub-seats aretapered or coned to bear upon the adjacent ends of the tapering rolls. Agroove is formed in the hub to clear thecollars upon the rolls, and therib is projectcd at the outer side of the groove to form the requiredshoulder. The cylindrical rolls may be made solid or hollow, intheformer case the ends being completely coni-. cal and bearing against aflat surface upon the larger end of the tapering rolls. hen thecylindrical rolls are hollow or tubular the ends are-tapered for thethickness of the tube and bear upon the ends of the tapering rolls inlike manner. VVit-h a casing fitted upon the outer sides of all therolls the bean ing is adapted to, resist thrust in one direction only,but two such constructions may he applied reversely to opposite ends ofthe The invention will. understood by reference to the annexed drawing,in which- Figure 1 a section on line 1-1 in Fig. :2; Fig. 2 in itsright-hand half is an end elevation of the hub and the rolls and cagethe'reon, and in its lefthand half a section n line 2-2 in Fig. 1. Fig.3 is a side elevation of the cage; Fig. 4 is a side elevation of thehub; Fig. 5 is a side elevation of one of the cylindrical rolls; andFig. 6 is a perspective view of one of the tapering rolls. Fig. (3 isperspective of a tubular roll; and Fig. 7 is a longitudinal section of awheel axle with the wheel-hub having opposite hearings in its oppositeends.

In Figs. 1 -'to 4 inclusive, the hub ais shown provided with thecylindrical seat 0, and the tapering seat 0 extended from one end ofsaid seat A groove (5 is formed at the opposite end of the cylindricalseat. An annular ridge 6 projects from" the hub at the rear edge of thesaid groove, and the depth of thegroove d below the seat b and the proection of the ridge 6 above the line of the seat are about equal.Cylindrical rolls f are fitted to the seat I) and tapering rolls 9 to'the seat 0. These tapering i rolls will be termed thrust rolls herein. Acasing h is formed with seats I) and 0' to fit the outer sides of thecylindrical and thrust rolls respectively. The inner corners of thecylindrical and thrust rolls contact atthe junction of the seats 6 andc, and the end of the thrust roll next such cornen'is'made' Thecontiguous end of the cylindrical roll is formed with a cone or taperishaped to make a rolling contact with the flat end-of the thrust roll.The opposite ends of the cylindrical rolls are formed each with a collarf to contact with the annular ridge 6 upon the hub, such collar andridge being beveled where they contact with one another, and the collarextending into the groove d so as to contact equally with the rib withinand outside the line of the seat. The bevel on the collar is marked 6.

The rib on the outer side of the groove forms a shoulder to resist thesliding tendency of the thrust rolls which is transmitted to thecylindrical rolls, and the portions of the collar which extendrespectively into the groove and which contact with the projecting ridgee, move respec-.

,lportions of the collar tend respectively to adi'nnce and-to retard thecollared end of the roll, and may in practice he made to .lialzince oneanother so that the collar produe es no tendency of the rolls 'to twistout of alineinent with the axis of the hub.

and the contactii'ig surfaces 'Phc cylindrical and thrust rolls arelocated in pairs so that each of the cylindriccl rolls may resist anyend movement of the contiguous thrust roll, and they are kept in aproper relation to one another-by a cage formed of a shell having acylindrical portion and an mtegrnl tape-ring portion 0', with flanges p,p

The use of such wings is coma hub, and my present improvement consisisin incl-ring such a cage with two portions one cylindrical and the othertopcring, so as to maintain cylindrical and tapering rolls in endengagement.

permit the end contact of the rolls ineach pair requires that theapertures s in the should be continuous or connected, that is, extendingthe entire length of both rolls; and to secure a frictionless rollingcontact of the rolls at their contiguous ends, they have end surfacesshaped respectively to'rotete at equal surface velocity so as notto'creete :iiny rubbing friction. To effect this, the larger ends of thethrust-rolls are. formed one-shaped and the larger ends ofthc'thrust-r'olls are made twice the diameter of the sloping side of thecone;

'wThe portions of both rolls-adjacent to the junction c of thecylindricgl and tapering seats necessarily revolve at'th'e samesp'eed,being located at the same axis of the'hub, of the rolls have the sameradius of contact, and thus roll to gethcr Without friction. Theconstruction thus effords *g rncans ofiesisting the end thrust with11;,mini1num of frictional resist- ,nnce.

'- 'lwo of the hearings may vhe employed to ,resistcnd thrust indifferent directions by xapplynig thcm to opposite ends of ushaftorgjournal. Such an application is shown 1H Fig. 7, where a wheel-centerA is repr seated in section with flanges B to attach V I i the spokes ofthe Wheel. The opposite ends of'the journal: C are nnideof, dilferentsizes to permit the assemblingnnd rcinovatof the ports by unscre'w'-isz-the cap D and nut upon the cndof the iournal.
